This morning, Time reported that Bergdahl's father, Bob, backed away from any criticism of the U.S. government's efforts to negotiate for his son's release from his Taliban captors.

"We do not want the American people to think we are dissatisfied with the way our government has proceeded," Bob Bergdahl told Time. "This isn't just about our son. This is about national policy."

He explained to Time that negotiations for his son's release were "extremely complex."

"It involves different parties—state actors and nonstate actors," said Bergdahl. "This is going to be difficult to reconcile, which is why we believe diplomacy for the hostages—and Bowe's not the only one, there are other hostages—are the window of opportunity here."
